Graphical user interface(GUI)

• In computing, a graphical user interface (GUI, sometimes pronounced gooey) is a type of user interface that allows users to interact with electronic devices with images rather than text commands.
• GUI's can be used in computers, hand-held devices such as MP3 players, portable media players or gaming devices, household appliances and office equipment.
• A GUI represents the information and actions available to a user through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation.
